No I'm not sure where the K11's airbag sensors are. Previous vehicles I have found them on, they were located under each of the front seats (dual airbag Y61 Patrol) with little dust boxes around them. N15 Pulsar (almera) with drivers airbag, i found its sensor under the driver's seat also.
I havent gone looking for the micra's sensor but I don't believe it would be positioned within the steering column itself. There's movement in that whole column in an accident, typically the sensors are mounted on a solid surface which doesn't deform in an accident.
They were on some late 80's/early 90's american cars. lol silly buggars.
